CARTON-FILLING MACHINE.

Specification of Letters Patent.

Patented Jan. 5, 1909.

Application filed. December 29, 1905. Serial 110,293,767.

To all whom it may concern:

Beit known that I, JOHN B. FALLON, Jr., of Boston, in the county ofSufiolk and State of Massachusetts, have invented an ImprovedCarton-Filling Machine or the Like, of which the following is adescription, reference being bad to the accompanying drawin 's, inwhich- Figure 1 is aplan view of part of a carton filling machineembodying my invention. Fig. 2 is a side elevation of the mechanismshownin Fig.1. Fig. 3 is a front elevation of the mechanism shown inFig. 1. Figs. 4 and 5 are details hereinafter described. Fig. 6 is adiagrammatic view of part of a filling and weighing machine, and ishereinafter-described.

In the case of carton testing machines as well as of carton filling andweighing machines and the like, the cartons are fed one at a time to themachine and tested or filled successively and it is desirable to depositin each carton a card or the like. i

The object of my invention is to provide automatic means to de osit acard 01' the like in each carton as it isled or tested-and to these endsI provide the testing or filling machine with a supplemental cardfeeding mechanism automatically operated in synchrony with the cartonfillin or testin machine so as to deposit a card or the like in .eachcarton.

time from a rank which is bodily advanced step by step as each carton isremoved from that rank to be filled and an important feature of myinvention consists in controlling the card feedingmechanism by theweighing mechanism of the machine so that the feeding of the cardsissynchronized with respect to'the feed of the cartons.

Otherfeatures of my invention are hereinafter ointed out.

Wit reference to the drawin s, A represents a portion of the circular tale of a cartonfilling machine, such for example as is shown anddescribed in U. S. Patent to Doble No. 716007, dated December 16, 1902.In the machine of this delivered onto table A from the constantlytraveling conveyer belt B by a shunter member C. That is, the cartonsare laced on the conveyer belt B by any suitab e means,

patent the cartons are and the constant movement of said conveyer in thedirection indicated by the arrow holds the end carton 1 against anabutment a. When the shunter O is reciprocated, as indicated by thedouble arrow in Fig. 1', this end carton is shunted from the conveyer Bonto table A into the position indicated by dotted lines in Fig. 1, andwhen shunter C returns to its norma position out of the path of the rankof cartons on the conveyer B, the latter shifts said rank bodily alonguntil the carton 2 is against abutment a. V

On the table A the cartons are picked up and carried forward to thefilling mechanism in the usual manner by mechanism not shown in thedrawings. Rails a and b b are provided to guide the cartons in theirmovements. As the cartons are shifted around table A they are deliveredsuccessively onto a scale-beam c where they are filled and Wei hed. Thescale-beam 0 acts through late ms 0 and c to control a rock shaft 0 onwhich is an arm 0 connected by a link with a shaft carrying a short arm0" connected by a link with a long arm 0 on a shaft 0 Shaft c carries anarm 0 that is connected with shunter C. A full description of theconstruction' and mode of operation of this mechanism can be found inthe patent above noted, it being only necessary to say here that wheneach carton is roperly filled its weight operates beam 0 w ich, throughthe intermediate mechanism described, shifts valve c so as to cause thepiston in cylinder 0 to move to the left until arm 0 acting throughclutch shifter c clutches member o to member 0 Thereupon gear ring isturned far enough to 1m art one revolution to inion c which acts tirough arms 0", c" an 0 and shaft 0" to operate shunter C as abovedescribed. At the completion of each revolution of inion c" shaft 0 isautomatically stoppe It will thus be seen that shunter C which controlsthe carton feed of the filling and weighing machine is in turncontrolled bythe weighing mechanism.

In accordance with my invention I pro- I vided for by connecting it withthe usual 4 videa bracket D fixed to the frame of the filling machine,and on this bracket iswise in 'bearingson-bracket D, and this pusherdelivers the cards to a pair of feed rolls d and d journaled on bracketDby which feed rolls the cards are projected through a chute d into thecartons. Pusher d has fixed to it an arm d connected with an arm d fixedto the shunter C. Theaxle of the lower feed roll a carries a pinion d inmesh with a rack d, the latter being connected'w'ith arm (I by a rod dsothat the. rack and pusher move together, With the rack feed roll d.,

i so- %uided in its to andfro movement by a anged wheel d on the axle ofthe upper Therefore each time the shunter moves to the left, Figs. 1 and2, to shift carton 1 from belt B to table A,'not only does pusherdengage the bottom card in receptacle d and carry the forward end ofsaid card between feed rolls (1 and d but the latter are rotated throughthe rack d and pinion d and deliver the card to chute d from which itdrops into carton 2, then at rest.

As shown in Figs. 4 and 5 the receptacle d is made with two side pieces(1 and d su e ported by upri hts d on bracket D. T e

ower edges of t ese two side pieces are made with inwardly turnedflanges d on which the cards at rest and the space between these twoflanges d serves as a passageway for the pusher d. The vertical edges ofthe two side ieces d and (i are also turned inward y so as to pocket thecards (Z and revent their lateral displacement, except t at the verticalflanges at one side of the receptacle are cut away as at d to provide apassageway for the bottom card when it is shifted by the pusher cl Thefeeding of the cards, as will nowbe seen, is in synchrony withthe-feeding of the cartons which in machines of this class is notusually uniform or regular owing to irregularities in the delivery ofthe filling to the cartons. Also it will be seen that the card is fed ata time when the rank of cartons on belt B is stationary, but when theshunter 0' shunter C, whereby the card feeding mechanism is accuratelytimed with respect to the movements of the rank of cartons on belt B todeliver each card at a'time when the rank is at rest. vMoreover, feedingthe cards into the cartons before they reach the filling mechanism andwhile empty makes it easier to place the card in the carton than wouldbe the case if the cards were inserted after the cartons were filled,although I do not mean to say that it is material to my invention in itsbroadest aspect whether the cards are deposited in the cartons before orafter the latter have been filled, or whether other additional materialinstead of cards is inserted in'the cartons.

What I claim is: 1

1. In a machine of the character described the combination of means. forremoving the first of a rank of cartons from the rank and supplementalmeans controlled by said re-o said s unter for automatically depositinga card or the like in the desired-cartons.

4. In a machine of the character described the combination of a shunterfor removing the first of a rank of cartons from the rank; a receptaclefor holding cards; supplemental feedin means for transferring the cardsfrom t e receptacle to the carton; and means connecting the feedingmeans with the shunter.

5.
